Abstract:
With the promise of automobiles that no longer depend on foreign gas and laptops that run three times as long without plugging in, it's no wonder electronics manufacturers, auto makers, and pioneering start-ups are scrambling to create the best fuel cell.

But PolyFuel, a Mountain View, California technology company, has approached the fuel cell problem from a different angle. It doesn't aspire to build a better power source, but rather to make current designs work better by refining its central component: the membrane.
